Cartilage regeneration using transforming growth factor-beta 3-loaded injectable crosslinked hyaluronic acid hydrogel.

Cartilage defects can be difficult to heal, potentially leading to complications such as osteoarthritis. Recently, a tissue engineering approach that uses scaffolds and growth factors has been proposed to regenerate new cartilage tissues. Herein, we investigated the application of hyaluronic acid (HA) gel loaded with transforming growth factor-beta 3 (TGF-β3) for enhanced cartilage regeneration.

The Taxonomy and Diversity of Proschkinia (Bacillariophyta), A Common But Enigmatic Genus from Marine Coasts.

Detailed morphological documentation is provided for established Proschkinia taxa, including the generitype, P. bulnheimii, and P. complanata, P.

Complete mitochondrial genome of a rare diatom (Bacillariophyta) and its phylogenetic and taxonomic implications.

We obtained the complete mitogenome of sp. strain SZCZR1824, a strain belonging to a poorly known diatom genus with no previous molecular data. This genome is 48,863 bp long, with two group I introns in and three group II introns in 1.

Influence of the tidal front on the three-dimensional distribution of spring phytoplankton community in the eastern Yellow Sea.

Hydrographic observation and biological samplings were conducted to assess the distribution of phytoplankton community over the sloping shelf of the eastern Yellow Sea in May 2012. The concentration of chlorophyll a was determined and phytoplankton was microscopically examined to conduct quantitative and cluster analyses. A cluster analysis of the phytoplankton species and abundance along four observation lines revealed the three-dimensional structure of the phytoplankton community distribution: the coastal group in the mixed region, the offshore upper layer group preferring stable water column, and the offshore lower layer group.

ARD1 binding to RIP1 mediates doxorubicin-induced NF-κB activation.

NF-κB is activated by several cellular stresses. Of these, the TNFα-induced activation pathway has been examined in detail. It was recently reported that receptor-interacting protein 1 (RIP1) is involved in DNA damage-induced NF-κB activation by forming a complex with the p53 interacting death domain protein (PIDD) and NF-κB essential modulator (NEMO) in the nucleus, although the underlying mechanism of this interaction has yet to be clarified.
